[PVE-User] pve-zsync error in path

[Tonči Stipičević]

Hello to all,
unfortunately I'm experineing this (error: in path) issue and cannot 
figure out why. My scenario is:
My hosts make in 3-node cluster. I want to use pve-zsync in order to do 
periodical fast incremental backups , what is not possible to achive 
with classical vzdump.

1. this is the source vm conf:
bootdisk: virtio0
cores: 2
ide2: rn314:iso/ubuntu-16.04.3-server-amd64.iso,media=cdrom
memory: 1024
name: u1604server-zfs
net0: virtio=1A:5D:FC:7C:FC:98,bridge=vmbr1
numa: 0
ostype: l26
scsihw: virtio-scsi-pci
smbios1: uuid=ba277e4f-9bc4-455b-bf9c-a8c96bb32391
sockets: 1
vga: qxl
virtio0: zfs1:vm-70020-disk-1,size=7G
/etc/pve/qemu-server/70020.conf (END)

2. this is the destination zpool (on server 10.20.28.4):
root at pvesuma03:~# zfs list
NAME USED AVAIL REFER MOUNTPOINT
bckpool 444K 449G 96K /bckpool
bckpool/backup 96K 449G 96K /bckpool/backup
root at pvesuma03:~#



3. this is the command I run on the "source" node:
root at pvesuma01:~# pve-zsync create -source 70020 -dest 
10.20.28.4:bckpool/backup --verbose --maxsnap 7 --name bck1
ERROR: in path
root at pvesuma01:~#
